I haven’t yet let my kids use those plugs but would like to leave my comment here for this company. When I contacted them by email to ask questions, I got a reply immediately. literally in 2 mins!! I thought I got an automated response but it was them answering all I wanted to know. I never had such an experience with any online stores. I could trust you right from the beginning! and I loved the option of payments included an etransfer! Thank you so much!!
